Questions about normal and light maps and retopo
show user profile  Joey Parker Jr.
So let's say I have a model and I'd like to create a normal map of it but the model has a turbosmooth set to 2 on it. Can I collapse it and make a normal of it?

Not only that but the unsmoothed model needs a lower poly count so I guess it needs to be retopologized.

And I also need to create a light map, I think. Not sure.

Any input is greatly appreciated. Also, I'm waiting to find out about the deadline and if it's too tight I may have to farm this out.

Don't collapse the turbosmoothed as you'll probably get a weird result due to unconnected verts.

Rather clone it and hide one version. You can then delete the turbosmooth for the other, delete some unneeded loops and get it optimal (plus unwrap, of course).

Then for baking unhide all and use max's RTT. You can use xnormal, but I'm a fan of RTT.

I don't know how much of this is redundant information for you, but here's a cheat sheet anyway:

For good normal and light map baking...
1. Apply a pure white, zero gloss material to your low poly (or everything in the scene, either way).
2. Use scanline.
3. With projection options use 2.5 Star Global supersampling, and untick "undersample..."
[edit] Oh yeah, and set the tangent to "up."
4. Apply a ground plane and a skylight.
5. In rendering options (F10)-> advanced lighting, use light tracer.
6. If you need a 1K map, render out a 2K map and shrink it after in PS.
7. With the projection cage reset it first and tick shaded as it will help you see if the cage is cutting through. Note: even if it looks okay rotate the camera around and if it pokes through at all push it out some more.

herfst1 - thanks! No it's not redundant. In fact I never do this stuff. I have another project that is occupying almost all my time so I might need your help if you're interested.
Send me an email. Address is on my website which is in my profile.

I probably won't get back to this until tonight (it's 8:30AM right now in ny) and I'm not sure what time zone you are but email me when you get a chance. As I remember you're half way around the world?
